Trying to compile a list of pine growers in the US, preferably ones that ship. Here are the ones I’ve located. Please add ones that I have missed.
Muranaka (eBay) CA
Brent (evergreengarden) CA
Chris (TelFarms) OR
Lone Pine Gardens
Bonsai NW (may not ship to east coast)
I’ve heard of others off the grid but locating them is challenging.
